Abstract

The invention discloses a tool and a method for detecting an installation angle error of a lead ring of an infrared detector. A lead ring is connected with a cold finger of an infrared detector. The tool for detecting the installation angle error of a lead ring of an infrared detector comprises a supporting part used for fixing a cold finger, and a measuring part connected with the supporting partand provided with an error measuring groove for detecting whether the installation angle error of the lead ring is within a reasonable range or not. According to the invention, compared with the traditional complicated detection method, the disclosed method has the advantages: detection efficiency is greatly improved; the time for each detection is reduced from 5 minutes to less than 1 minute; the occupation of equipment and labor in the process can be reduced; and the assembly production cost is reduced, so that the lead ring installation angle error control capability can be effectively improved, the performance limitation of a final finished product caused by unqualified products is avoided, the use fault of the whole machine caused by external wiring pull-apart is reduced, and the development of high-quality miniaturized infrared detection equipment is further promoted.

Description

technical field [0001] The invention relates to the field of infrared detectors, in particular to a tool and a method for detecting the installation angle error of an infrared detector lead ring. Background technique [0002] With the development of infrared technology, infrared detectors are used in many fields such as infrared astronomy, automobile driving, medical imaging, forest fire prevention, and process monitoring. The infrared detector mainly converts the optical signal in the infrared band received by the target object into an electrical signal through a semiconductor device, and then uses a readout circuit to lead the electrical signal in the chip to the outside of the Dewar through the lead ring component and then proceeds to the amplifier circuit. Infrared imaging processing. [0003] With the improvement of application requirements, the infrared detector is developing towards the direction of compact structure and miniaturization. The lead ring is used as a br...
